U6xx
editProduction of the U660E and U660F commenced in January 2006, Toyota's first 6-speed automatic transaxles for front-wheel-drive vehicles; transaxles feature a compact gear train that achieves six speeds using a single axis to produce a high torque of 400 Nm, and are as low cost, compact, and light as 4-speed automatic transaxles[1] The transaxle is a Lepelletier design which uses a simple gear set to drive a Ravigneaux planetary gear set (with long and short pinion gears in the same planet carrier).[2]

UA80E · UA80F · UB80E/F
editProduction of the UA80E and UA80F commenced in August 2016. This transaxle features a compact gear train that achieves eight speeds using a single axis allowing for input torque up to 430Nm. It is a more compact and optimized version of the U880 automatic transmission structure with additional features for improved performance and efficiency. The marketing name for the transmission is the "Direct Shift – 8AT 8-speed automatic transmission"[3][4] Unlike the U880 transmission, which was developed for Toyota by Aisin AW, the UA80 was developed in a joint venture between Toyota and Aisin AW. Due to global application, development was done in a global fashion involving engineering resources in both Japan and the US. The UB80E/F transmissions are used for lower torque applications, 4 cylinder engines, and rated at 280Nm.[5]
UA80 Failures and Problems
editThe UA80 family of 8 speed transmissions has had some issues which led to class action lawsuits, a Customer Support Program and numerous TSBs. Starting in 2017, some Highlander and Sienna customers starting complaining of harsh or delayed shifting, delayed acceleration, hesitation, jerking, unintended acceleration, lurching and excessive revving before upshifting. [6] [7]
Additional issues arose when 2017 & 2018 Highlander and Sienna customers experienced whining, master warning lights/check engine lights and transmission failures. This prompted Toyota to initiate a Customer Support Program (ZJC). This program covered certain 2017 and early 2018 built Highlanders and Sienna under specific VIN parameters and transmission build dates. [8] However, this issue has been problematic beyond the scope of the ZJC program. This is causing out of pocket costs for customers outside of the standard 6 year / 60K mile powertrain warranty. [9]
More whine or grind issues have been documented in 2021 Avalon, Camry and Highlanders equipped with the UA80E or UA80F transmission prompting T-SB-0008-21. [10]
